Don'??t Give Out Your Email, Phone Number, Or Zip Code When Asked

Obviously, if a sketchy dude in a bar asks for your phone number, you say no. But when the asker is a uniform-wearing employee at Best Buy, many a consumer hands over their digits when asked. Stores often use this info to help profile you and your purchase. You can say no. If you feel badly about it, just pretend the employee is the sketchy dude in the bar.
